rock drill pneumatic rock drills (pneumatic rock drill 1m distance of
the sound pressure level of 110db (a) above), but still higher than90db
(a), up to 100db (a) around, and the sound energy concentrated in the 1
~ 5khz frequency segment does not exceed the human ear is sensitive
frequency range, if not take the well drilling rigs for sale noise
protection measures body of workers is still harmful. Hydraulic rock
drill pilot study noise source of the noise generated by the impact
mechanism broken rock noise, the noise generated by the rotating
mechanism and drill bits. Noise generated by the impact mechanism
striking piston solder tail closed space generated jet noise, impact
structural noise generated after the piston impact solder and is
deformed due to an down the hole drill rig impact surface is generated
around the pressure pulse noise, wherein the structure-borne noise is
the main ingredient noise frequency characteristics of the structural
vibration frequency consistent. The slewing mechanism noise from the
slewing mechanism hydraulic and mechanical noise, but the noise
intensity lower than the noise generated by the impact mechanism, sound
pressure level difference of more than 10db (a), so little effect on the
hydraulic rock drill noise evaluation. The drill head broken rock noise
generated hydraulic rock drill noise test chiseled into the rock drill
head 0.5m deep, this effect is negligible. Therefore, the research,
testing and analysis of hydraulic rock truck mounted drilling rig drill
noise, mainly focus on the noise generated in the shock structure.
Experimental study on hydraulic rock drill impulsive noise and its
impact mechanism vibration frequency characteristics test and analysis
of well drilling trucks for sale hydraulic rock drill noise is mainly
related to the size of the impact energy and impact frequency has little
effect. Since under certain conditions, the impact of the hydraulic rock
drill size depending on the working pressure, to select the appropriate
working pressure is the key to reduce the noise of the hydraulic rock
drill. Hydraulic rock drill noise is caused mainly by the structure of
the noise, the
